BACKGROUND OF THE INVENTION TECHNICAL FIELD

This invention relates to the administration of medicaments. Morespecifically, the invention relates to a smart capsule system fordelivery of drugs or other materials to a user.

DESCRIPTION OF RELATED ART

Drug dispensing apparatus and methods have been proposed in which a drugis contained in an enclosed ingestible or insertable capsule. Anactuator and controls are also disposed in the capsule, to dispense thedrug from the capsule at some specified time or upon a specified event.To date, engineered capsules with mechanical or electronic dispensingand sensing components have been proposed and studied that may beeffective at releasing a drug or other medicament at a specifiedposition along the alimentary canal. These controlled released capsuleshave been proposed in many number of ways, but all are similar in thatthey tend to be quite complex. The complexity results in a very highcost of manufacture and assembly, and uses to date have generally beenlimited to research and development. However, the controlled release ofthese capsules would be extremely beneficial in everyday usage fortreating maladies of the alimentary canal, or even more broadly fordispensing any type of medication within a body cavity, such as at adesired position along the alimentary canal. However, as noted above,the cost associated with the complexity makes this impractical.

Accordingly, there is a need in the art for a low cost electroniccapsule that could be used to dispense drugs intended to be taken atsome determined time or interval.

Another drawback associated with conventional drug delivery systems, isthat the user may administer as many doses as he desires, and inwhatever interval they see fit. This is true even if theself-administered dosaging does not comport with recommended amounts.This can lead to ineffective treatment, and in some extreme examples,overdosing or unintended dependency.

Thus, there also is a need in the art for a medicament delivery systemin which dosing of drugs is recorded and allowed only at specific times.

SUMMARY OF THE INVENTION

The present invention addresses the foregoing needs in the art byproviding a medicament delivery system and methods that include alow-cost, controllable capsule, usable in any number of applications,including daily, generally low cost drug delivery.

In one aspect of the invention, a system for administering a medicamentincludes a plurality of capsules, a capsule dispenser, and a capsuleactivator. Each of the capsules includes a reservoir containing amedicament and an outlet in communication with the reservoir throughwhich the medicament exits the capsule. The capsule dispenser releasablycontains the ingestible capsules and is adapted to dispense the capsulesto a user in accordance with a predetermined schedule. The capsuleactivator activates the dispensed capsules prior to administration tothe user.

In another aspect of the invention, a method of administering amedicament to a user includes storing a plurality of capsules in astorage unit, dispensing at least one of the capsules from the storageunit to a user, activating the capsules prior to their administration tothe user, and releasing the medicament from the reservoir afteradministration of the capsule to the user.

These and other features, aspects and embodiments of the invention willbe better understood with reference to the appended drawing figures andfollowing detailed description of the invention in which preferredembodiments of the invention are shown and described.

DETAILED DESCRIPTION OF THE INVENTION

As noted above, the present disclosure relates to medicament deliveryand more particularly to systems and methods for administering amedicament to a patient. The term medicament is used herein to mean anysubstance that can be administered to a user via a capsule. Medicamentsinclude, but are not limited to, pharmaceutically active compounds,drugs, dyes, radio-labeled markers, vaccines, physiological markers, anddiagnostic agents.

The systems and methods of the disclosure are preferably more economicaland robust than existing systems employing engineered drug deliverycapsules, while still providing the flexibility, reporting functionalityand control offered by existing electronic capsules. Preferredembodiments of the present invention generally provide drug deliverycapsules with external intelligence.

FIG. 1 shows a first embodiment of the invention, including a medicamentdelivery system 10 having an electronic capsule 20 and an externaldevice 50. The external device 50 is so termed only because, unlike thecapsule 20, it is not intended for administration to the user, 10 e.g.,by ingestion or insertion. The many features and functionalities of thecapsule 20 and the device 50 will be described in more detail, asfollows.

An embodiment of the capsule 20 is illustrated in FIG. 2. The capsule 20is sized for ingestion by or insertion into a user. It preferablyincludes a reservoir 22 for storing a medicament (not shown) to beadministered to the user, an outlet 24 through which the medicament isdispensed from the reservoir 22, an actuator 26 for aiding in dispensingof the medicament, and controls 28. The reservoir is initially closed,and in some embodiments sealed, such as by a cap 25 covering the outlet24 to separate the medicament from the environment. In alternativeembodiments, some of which will be discussed below, additional featuresand components may be included in the capsule, but their inclusion mayoperate to increase the cost of the capsule. As noted above, in someembodiments of the invention the cost of the capsule is kept as low aspossible, as the capsule 20 is the disposable piece in the system 10 andkeeping the cost of the capsule down will enable the system to be usedin a broader range of medicament dispensing applications.

The reservoir 22 and outlet 24 preferably are arranged in a conventionalmanner, with the actuator 26 applying pressure on the contents of thereservoir 22 to cause the medicament to dispense through the outlet 24.More specifically, as the medicament is pressed by the actuator againstthe cap 25, the cap 25 is subjected to a force sufficient to expel thecap 25 from the capsule 20, thus allowing medicament to exit through theoutlet 24. The controls 28 may take many forms and be of varyingcomplexity, but preferably are arranged to control the actuator todispense the medicament. In their various forms, some of which will bedescribed in more detail below, the controls 28 may include a powersource, such as a battery, an induction coil, or a capacitor, a receiverfor receiving instructions to control the actuator to dispense themedicament, and a transmitter for transmitting information, such as anindication that a medicament has been delivered or information about acondition of the capsule.

The capsule may also include any number and manner of sensors (notshown). For example, the capsule may have sensors that detectenvironmental conditions, such as moisture, pH, and temperature. Suchenvironmental sensors may be active in that they continuously report onthe condition they are designed to monitor, but more preferably they aredesigned as “binary” sensors that change state upon some conditionchange. For example, the sensor may include a polymer that erodes in thepresence of a specific condition, such as an elevated pH. This erosioncauses a detectable short circuit, which detection may be used to turnon the electronics in the capsule. Using this type of sensor willconserve energy over the active sensors mentioned above. Sensors mayalso be included in or on the capsule, which confirm that the medicamentis present in and/or has been discharged from the capsule.

In FIG. 2, the reservoir 22 is defined by a sidewall 21 of the capsule20, the cap 25, and a movable plunger 32. The outlet 24 is an open endof the capsule 20. In other embodiments, the reservoir may be a bladderor lining disposed in the capsule. Moreover, the outlet 24 may be asmaller aperture or a plurality of apertures. The outlet 24 may openthrough the sidewall 21 in addition to or instead of through the capsule20.

In this embodiment, the actuator 26 includes a spring 30 (shown coiledin FIG. 2), the plunger 32, and a filament 34. Before dispensing themedicament from the capsule 20, the spring 30 is retained in a retractedposition, which is the position illustrated in solid lines in FIG. 2.The plunger 32 is disposed contacting the spring 30, between the spring30 and the reservoir 22. The filament 34 is fixed to the plunger 32 andto the body of the capsule 20. According to this arrangement, thefilament 34 fixes the position of the plunger 32 longitudinally alongthe capsule 20, and the plunger 32 acts against the force of the spring30 to retain the spring in the compressed position.

A heating element 36 also is provided in the capsule of FIG. 2,proximate the filament 34. The filament 34 is a meltable filament thatmelts after being warmed by the heating element for a sufficient timeand at a sufficient temperature. Without the connection provided by thefilament 34, the plunger 32 can no longer retain the spring 30 in thecompressed position, so the spring extends, driving the plunger 32 to anextended position (not shown in FIG. 2). The actuated plunger hassufficient force to press the medicament in the reservoir 22 against thecap 25 to expel the cap 25, thereby expressing the medicament throughthe outlet 24. The heating element 36 may be any conventional heater,although a preferred heating element is a resistive heater that isincorporated into the controls disposed in the capsule. The heater ispreferably powered by an on-board power supply, which is alsoincorporated into the controls. In other embodiments, the filament couldbe broken by means other than melting. For example, the filament couldbe broken such as by cutting, dissolving, chemical reaction, or anyother means. The invention is not limited to the illustrated filament.Any latch or stop capable of retaining the spring in the compressedposition and which can subsequently be moved, removed, or destroyed torelease the spring may be used.

In FIG. 5, a capsule substantially the same as the one illustrated inFIG. 2 is provided. Different from FIG. 2, however, is that FIG. 5 alsoschematically illustrates a switch 40. The switch 40 is provided to turnon the heater 36. In its simplest form, the switch completes a circuitto allow power to the heater 36.

FIGS. 6 and 7 illustrate two embodiments of the switch 40. Each includesa flexible electrode 42 and a stationary electrode 44. When the twoelectrodes come into contact, a circuit is completed to provide powerto, and thus turn on, the heater 36.

In FIG. 6, a dissolvable material 43 is provided between the flexibleelectrode 42 and the stationary electrode 44 to bias the flexibleelectrode 42 away from the stationary electrode. The material 43 ischosen to interact with a specific environmental condition within thebody, e.g., a fluid of a specific pH. This interaction melts thematerial, and the flexible electrode 42 returns to an unbiased position,contacting the stationary electrode 44.

In FIG. 7, an expandable material 45 is provided between a wall 21 ofthe capsule and the flexible electrode 42. As the material 45 expands orswells, e.g., due to absorption of water or some other bodily fluid, theflexible electrode 42 is biased toward the stationary electrode 44,eventually resulting in contact of the two.

As will be appreciated by those having ordinary skill in the art, thecapsule described herein is but one example of a relatively low-costcapsule effective to dispense a medicament at a desired time. Othercapsules may also be used in the system of this disclosure, withoutdeparting from the disclosure's spirit and scope. In one alternativeexample, the capsule may not include a spring at all, but instead thecap or a similar covering is dissolved in a predetermined environment.Once the covering is dissolved, the medicament is unrestrained anddiffuses or otherwise exits the capsule. In another embodiment, anactuator such as a compressed spring opens a valve allowing fluid fromthe environment to rush into the capsule. As a result of that rush, asecondary, more powerful actuator is actuated to force the medicamentout of the capsule. In still another embodiment, the actuator mayinclude a gas-forming or osmotic pressure engine that acts to push themedicament from the capsule. Moreover, although a mechanical trigger isillustrated in FIGS. 6 and 7, a timer may instead be used to trigger anactivation of the heater.

As noted above, the capsule 20 is used as part of a medicamentdispensing system 10, which also includes the external device 50. In apreferred embodiment, the capsule 20 is simple in construction andoperation, and thus lower in cost, but the system 10 is verycomprehensive. Accordingly, the external device 50 is configured toaccomplish much of the functionality of the system, other than actualdispensing.

As illustrated in the schematic top view of FIG. 3, the external device50 includes a receptacle 52 that is sized and configured to store aplurality of the capsules 20. The capsules 20 may be provided in aunique package, such as a cartridge, for ready insertion into thereceptacle 52, but the manner of retaining the capsules 20 in thereceptacle is not limited. The external device 50 also includes anaccess opening 54 through which the user accesses the capsules 20 storedin the external device 50. The access opening preferably allows the useraccess to less than all of the capsules 20, and more preferably allowsaccess only to the capsule or capsules that are to be administered at agiven time. Thus, the external device 50 also acts as a dispenser of thecapsules 20, similar to a conventional vending machine. Although notillustrated, suitable mechanical and electronic components may beincluded and/or required to achieve this dispensing feature. Suchfeatures may be similar to those found in conventional pill dispensingfeatures, such as the PHILIPS@ Medication Dispensing Service.

The external device 50 preferably also includes a capsule activator 56.The capsule activator 56 renders each capsule capable of dispensingmedicament. That is, at the time of insertion into the external device50, each capsule contains an amount of medicament, but is passive andthus unable to dispense the medicament. Put another way, the passivecapsule locks the medicament inside and will not normally dispense themedicament until it is unlocked. Thus, upon being placed in thereceptacle 52, the capsule is in a passive, nondispensed state. Thecapsule activator 56 changes the capsule to an active, non-dispensedstate. In one presently preferred embodiment, the capsule activator is acharger that charges a power source on the capsule. For example, thecapsule activator may inductively charge an induction coil or inductionbank or charge a capacitor contained in the capsule. In anotherembodiment, the capsule activator may “wake up” or “power on” thecapsule's power supply and/or electronics, such as by activating aswitch on the capsule. In still another embodiment, the capsuleactivator charges the actuator, such as by pre-loading a spring. Othermeans of activating the capsules may also be contemplated. As will beappreciated, the activation feature of this disclosure has otherbenefits, as well. For example, if a user takes a capsule that is notactivated, it will not dispense its contents, because those contents arelocked inside. Controlled activation will prevent accidental overdoses,and could help curb narcotic abuse.

In one embodiment, the capsule activator 56 is integrated with thedispensing function of the external unit. For example, the capsuleactivator 56 is arranged proximate the access opening 54 such that thecapsule is activated at the time the capsule is accessible to the user.The capsule activator may be provided in the form of a port or cradleinto which a to-be-dispensed pill is placed for activation, and thisport or cradle can be arranged at the access opening 54. In anotherembodiment, the activation port is upstream of the access opening 54.For example, an activation port serving as the capsule activator 56 maybe inside the external device 50 where it activates the capsule prior tothe pill being presented to the user at the access opening 54.

In still another embodiment of the invention, the capsule activator 56may operate separately from the dispensing function. For example, acapsule may be dispensed to a user via the access opening 54, at whichtime the user places the capsule in the capsule activator 56. In thisembodiment, visual, audible, or other indicia may be provided inconnection with the capsule activator 56, to alert the user that thecapsule is activated.

The external unit 50 allows for controlled dispensing and activation ofcapsules. To this end, the external unit 50 preferably includes aprogrammable memory 58 for storing a medicament administration profile.This profile provides the schedule that dictates when the capsules areto be activated and/or dispensed. The profile may be determined based onthe drug, characteristics of the user, or some combination of the two.In preferred embodiments, the medicament administration profile isuploaded to the external unit, e.g., by a computer interface, the user,the medicament administrator, the prescribing doctor, a pharmacist, orthe drug manufacturer/packager. When an interface is provided, theprofile may be updated as prescriptions or conditions change. In otherembodiments, the dispenser may be pre-programmed with the administrationprofile, and unchangeable by the user.

The external unit preferably also includes a clock 60. Most medicamentadministration profiles include a frequency of drug administration. Theclock 60 is used to time dispensing and/or activation based on theadministration profiles. The clock also may be used to establish arelease time for the medicament. For example, the clock 60 may be usedto determine an elapsed time after activation or after ingestion, whichelapsed time could be predetermined and used to instruct release of themedicament from the activated capsule, for example by activating theheater of the capsule of FIG. 2.

The external unit 50 may also include a receiver 62 and a transmitter64. The receiver 62 may be of any conventional arrangement, includingbut not limited a wired or a wireless receiver. In one embodiment, thereceiver is configured to receive the medicament administration profile.The receiver also may receive information from an activated capsule,including but not limited to, information relating to a position of thecapsule, confirmation that the capsule has dispensed its medicament, andinformation that the capsule has been ingested. Information received bythe receiver may be stored by the external unit 50, such as in memory(not shown).

The transmitter 64 may be used to transmit instructions to an activatedcapsule to release the stored medicament. The transmitter 64 also may beused to transfer any information stored on the external unit, forexample, to a caregiver or technician, such that stored information canbe reviewed for diagnostic purposes.

The external unit 50 preferably also includes some number of userinterfaces and/or user indicators. In the illustrated embodiment, theexternal unit 50 includes a light 66 as a visible indicator. The light66 indicates when a medicament is to be administered. Thus, when therelease profile, in conjunction with the clock, determines that amedicament is to be administered, the light 66 will illuminate. Othervisual indicators, such as digital displays, touch screen displays, andthe like, may also or alternatively be used. Moreover, the indicator isnot limited to a visual indicator. An audible alarm may also oralternatively be included in the external unit 50.

While the inventors contemplate that a capsule may be dispensed and/oractivated when the user receives the indication that the medicament isto be administered, in some embodiments, the user will first acknowledgethat the indication has been administered. To this end, a dispensebutton 68 is provided on the external display. The user pushes thedispense button 68 upon receiving an indication that it is time toadminister the medicament and the unit dispenses the capsule. Asdescribed above, activation may also occur at the time of dispensing.

As just described, a preferred system according to the disclosureincludes two components, namely, a capsule and an external unit. Thedisclosure is not limited to this arrangement. The external unit mayconsist of more than one component. For instance, when the capsule hasone or more of a transmitter and a receiver, the user may be required toremain in close proximity with the external unit, to allow forcommunication. So the user is not tethered to one location, he may beprovided with a wearable module that, among other features, facilitatescommunication with the capsule. A separate, stationary module would thenbe provided, to perform other functions of the external unit describedabove, such as dispensing and activation. The features and functions ofthe external unit may be parsed among any number of modules, as designdictates.

Methods of administering a medicament using the system 10 describedabove now will be described, with particular reference to the flow chartof FIG. 4.

In step 110, the external unit determines that it is time to administera capsule. This is done using information from the aforementioned anddescribed medicament administration profile. This determination willlikely also include inputs from the clock or other sources.

In step 120, the user is alerted to the fact that it is time toadminister the medicament. In the embodiment discussed above, the useris notified when a light on the external unit 50 is turned on.Alternatively, the user could be notified by an audible indicator. Instill other embodiments, the external device could notify the user bysending a message such as a text or email message to a device carried bythe user.

In step 130, the capsule is prepared for activation. For example, it maybe placed in a port or cradle that will act as or in connection with thecapsule activator described above. In a preferred embodiment, thecapsule is automatically placed, i.e., by a mechanism in the externalunit, in to the port or cradle. In other embodiments, step 130 mayinclude presenting a passive capsule to the user, who manually transfersthe capsule to the capsule activator or who manually activates thecapsule, e.g., by activating a switch on the capsule.

In step 140, the capsule is activated. As will be appreciated, prior tothis step, the capsule is preferably passive or dormant. That is, itwill not dispense the medicament absent some unauthorized external forcethat operably destroys the capsule. Only after the capsule is activated,in this step 140, will the capsule be prepared to dispense themedicament as intended. In some embodiments the capsule may be activatedby being coupled to an energy source, with energy from the source beingstored in the capsule for functional operation. For example, the capsulemay be plugged in to charge a battery or capacitor stored therein, orthe battery or capacitor may be charged inductively. The activation mayalso be done by changing an electrical or mechanical switch, such asfrom an “off to an “on” position

In step 150, the capsule is administered to the user. In a preferredembodiment the user ingests the capsule, but other means ofadministering the capsule, such as by rectal or vaginal insertion, arealso contemplated.

In step 160, the capsule receives information that a triggering eventhas occurred. The triggering event may be any number of events,including but not limited to activation of the capsule (step 140) oradministration of the capsule (step 150). Administration of the capsulemay be detected by including a moisture-detecting sensor on the capsuleto determine when the capsule enters the relatively moist environment ofthe user's alimentary canal. The user may also manually verify that headministered the capsule, such as by pressing a button on the externalunit. In another embodiment, the capsule may include a pH sensor, anddetection of a certain, predetermined pH value will be the triggeringevent.

After detection of the triggering event, in step 170 the capsuledispenses the medicament such as by opening the capsule's reservoir, asdiscussed above. Dispensing may occur immediately upon the triggeringevent or it may happen at some predetermined time after the triggeringevent.

In step 11 80, the capsule reports that the medicament has beendispensed. It may do this by sending a signal, e.g., by RF transmission,to the external unit. In other embodiments, a state of the capsule maybe changed when the medicament is released, and the user may note thischange in state when the capsule is passed. The indication that themedicament has been dispensed may be a binary indication, or it may bemore in depth, depending upon the sensing capabilities of the capsuleand the external unit. For example, the indication that the medicamenthas been dispensed may include a location of dispensing, a time ofdispensing, and/or any other pertinent information. This step 180 maynot be required at all in some embodiments, for example, if there issufficient confidence that an administered capsule will functionproperly.

In step 190, the external unit starts a timer that will establish whenthe next administration of the medicament is to take place. The timermay be started when administration of the medicament is determined, instep 180. In other embodiments, the timer may be started when a capsuleis dispensed, when a capsule is activated, when a capsule is ingested,or upon the triggering event occurring in step 170.

The methods just described, and variations thereof, are effective ataccurately administering medicaments to a user according to apredetermined schedule. The improved methods inhibit improperadministration of medicaments. Moreover, each of the steps is preferablystored in a memory of the external unit, thus allowing a user orcaregiver the ability to track and confirm administration of themedicament. This knowledge is particularly valuable when coupled withother information about the user, because it allows for accuratediagnosis and indication of treatment regiments.

Moreover, although presently preferred embodiments of the disclosurehave the bulk of the intelligence of the system in the external unit,such is not required. In one alternative embodiment, the capsule mayinclude a memory storing the administration schedule, such that it neednot receive instruction from the external unit to dispense themedicament. Similarly, a small processor may be provided in eachcapsule, such that the capsule detects the triggering event and as adirect result of the triggering event, or after some elapsed timecalculated by a clock in the capsule, releases the medicament.
